HBAR, I think you could get away with that in the older vehicles easier.

I don't know if this system is fixed orifice or expansion block, and it's my suspicion that the system ran *weak* for a little while before it blew up. It could have been dumping bits and pieces of plastic compression ring and aluminum into the system for a little while. IF that's the case, then everything ahead of the block/orifice might have to be replaced as well for maximum efficiency again. (accumulator and condenser)

Hopefully it just broke and that was the end of it.

Just my two cents.
